Meaning

WordPress stores active plugins by path (folder/file.php). Renaming plugin folders (often to disable them during troubleshooting), failed updates or deployments without the plugin cause automatic deactivation.

Common causes

  • Plugin folder renamed or deleted
  • Failed update leaving a partial folder
  • Deployment missing the plugin
  • Case-sensitive path change after moving servers

⚡ Quick fix

  1. Restore or reinstall the plugin
  2. Rename the folder back
  3. Reactivate in Plugins

Detailed fix by platform

Shell

  1. php
    wp plugin list --status=inactive
wp plugin install woocommerce --activate

How to diagnose

  1. Folder — Exists with the expected name?
  2. Deploy — Included?
